Couple months ago (when i was playing wow), I got to playin one day and I blackscreened almost immediately. Shook it off and rebooted. Was playing for about 10 minutes and froze. Whole comp froze. Rebooted and while Windows was loading (at the desktop) it blackscreened. Checked my temps (fine), my volts (fine), and ran malware/spyware/virus scanners.
Couldn't find ANYTHING wrong. Left it that night sitting in windows, got up next morning and everything was looking good. Surfed the forums, checked the news, loaded up WOW. Played for about an hour and BAM, lockup. Rebooted, played again for about 3 hrs np. Next day I woke up to it blackscreened.
Ok, so since i've been building system for about 18 yrs, I got into my stash of goodies. Figured must be Video related cause thats when it mostly happens is under extreme video. Does same thing with another vid card. Decided to run a memory check. Halfway through it blackscreened. Great, think I might have some flawed memory.
Got my memory in a week later, fired up and.....played wow for 15 min before BLACK SCREEN!!!!. Well crap. Thinking MAYBEY my PSU MIGHT be issues, I reordered another on. A big 700watter. Nope.
Finally in desperation I reordered a new motherboard...... Haven't had a problem sense lol.
I never really had a problem like that before. Initial test codes came up fine on boot and a couple testing programs I have gave it flying colors in tests. It acted JUST like a heat or, as someone mentioned, a voltage rail problem.
If its not ur PSU, ask a friend to borrow components just to check something out (memory stick, vid card, etc) and just go down the line and eventually you'll get it.
Good Luck
